Sulfonyl

A sulfone. It consists of a sulfonyl group bonded with two hydrocarbon substituents.

A sulfonyl group can refer either to a functional group found primarily in sulfones or to a substituent obtained from a sulfonic acid by the removal of the hydroxyl group similarly to acyl groups. Sulfonyl groups can be written as having the general formula R-S(=O)₂-R', where there are two double bonds between the sulfur and oxygen.

Sulfonyl groups can be reduced to the hydrocarbon with lithium aluminium hydride (LiAlH₄).

In inorganic chemistry, when the group -S(=O)₂- is not connected to any carbon atoms, it is referred to as sulfuryl.

Examples of sulfonyl group substituents

The names of sulfonyl groups typically end in -syl, such as:
